Koehler K10403 Solid Block Oxidation Stability Bath for Gasoline and Fuels, 4-Place. 115V/60Hz. This Solid Block Bath provides an indication of the tendency of gasoline and aviation fuels to form gum in storage. The sample is oxidized inside a stainless steel pressure vessel initially charged with oxygen at 100psi (689kPa) and heated in a solid block bath. The amount of time required for a specified drop in pressure (gasoline) or the amount of gum and precipitates formed after a specific aging period (aviation fuels) is determined. Insulated aluminum block baths available in two or four-unit capacity. Baths feature microprocessor temperature control with built-in overtemperature protection and dual LED displays for set point and actual temperature values in °C/°F format. The solid block design offers operating advantages over the boiling water bath, and meets temperature control and other requirements of ASTM and related methods. It should be noted, however, that many applicable specifications for this test method call for a liquid bath medium. Housed in an insulated steel cabinet with chemical-resistant polyurethane enamel finish. Includes lids for pressure vessel ports. Maxiumum teperature: 250°F (121°C). Order thermometer separately. Conforms to the specifications of: ASTM D525, D873; IP 40, IP 138; ISO 7536; DIN 51780, 51799; FTM 791-3352, 791-3354; NF M 07-012, 07-013. 115V/60Hz.
